changed my mind here and updated this comment to suggest
GetDefaultFontRenderParamsForWebContents() so it matches the param to
GetCustom...()

 GFX_EXPORT const FontRenderParams& GetDefaultWebKitFontRenderParams();
 
-// Returns the system's default parameters for WebKit subpixel positioning.
-// Subpixel positioning is special since neither GTK nor FontConfig currently
-// track it as a preference.

added a TODO here to also accept a style, since we can pass bold/italic to
fontconfig as well
